Problem with Kinesis Video Stream PutMedia OPTIONS request.

Hello,

I got 404 on POST https://s-######a.kinesisvideo.eu-central-1.amazonaws.com/putMedia request:

1. OPTIONS request: https://user-images.githubusercontent.com/86299738/145280743-18ab38a7-0981-44e1-b3ca-fab52bcca98b.png

2. Main request(which induces the OPTIONS request): https://user-images.githubusercontent.com/86299738/145280462-9bbca7b5-a68d-41fd-aa27-6e2827250a6a.png

This documentation https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/API_dataplane_PutMedia.html

doesn't state whether the endpoint should handle the OPTIONS request or not.

Should I expect a response on the KVS <DataEndpoint>/putMedia OPTIONS request?

Detailed info about my attempts in this issue https://github.com/aws-samples/amazon-kinesis-video-streams-demos/issues/143#issuecomment-988313055

Is it still possible to stream to KVS from a browser?

Thank you
